  • Patent number: 9911198
    Abstract: At least one method of, and at least one apparatus, system and computer readable medium for, matching moving targets between two camera views are discussed herein. The moving targets are tracked over video frames in each of the camera views and motion directions of the targets are recorded. Appearance similarities for cross-camera target pairs over synchronized ones of the video frames are determined. A joint probability model of co-occurred ones of the recorded motion directions for the camera views are determined using a weighted accumulation of the recorded motion directions of the cross-camera target pairs, where accumulation weights used in determining the joint probability model are derived from the determined appearance similarities. The moving targets between the camera views are matched using the joint probability model.

  • Publication number: 20180060669
    Abstract: A method and system associated with a camera view of a moving-object in a scene. The method comprises detecting and tracking the moving object over multiple video frames, estimating an orientation of the moving object in each of the video frames, and constructing a cost map from the estimated orientations over the multiple video frames for finding a minimum cost path over the cost map. The Method also comprises determining regularised orientation estimates of the moving-object from the minimum cost path, and locating the vanishing point of the camera view based on an axis of the moving-object from the minimum cost path, the axis formed by using the regularised orientation estimates.

  • Publication number: 20180050077
    Abstract: Plasmonics-active metal nanostars are provided that can be used for treating and detecting cells in a subject. The modes of treatment include a photo-activated drug, which is activated by the photo-response of the nanostar to electromagnetic stimulation; a thermally-activated drug, which is activated by a thermal response of the nanostar to electromagnetic stimulation; and the thermal response of the nanostar itself to electromagnetic stimulation, which may directly or indirectly cause the death of an undesirable cell. Uptake of nanostars by undesirable cells may also aid in detection, by enhancing contrast or otherwise transforming electromagnetic stimulation during imaging.

  • Patent number: 9893659
    Abstract: A circuit includes a driver circuit having a high side switch device and a low side switch device coupled to a load voltage node and a motor winding output. A controller operates the high side switch device and the low side switch device. The controller operates in a normal mode to supply current to the motor winding output for driving a motor winding when an external power supply is available to supply the load voltage node. In response to detecting a loss of the external power supply, the controller operates the high side switch device and the low side switch device in a boost mode to utilize a back electromotive force (BEMF) voltage from the motor winding to supply current to the load voltage node.
